Definitions
- PEG Poly(ethylene glycol)
- the present invention provides compositions of activated water-soluble polymers.
- an activated water-soluble polymer comprising a water-soluble polymer covalently attached to an activated leaving group wherein the water-soluble polymer is a member selected from PEG, PPG, PEG derivatives, and PPG derivatives, and the activated leaving group is a member selected from
- polymer refers to any of numerous natural and synthetic compounds of usually high molecular weight consisting of repeated linked units, each a relatively light and simple molecule.
- activated leaving group refers to those moieties which are readily displaced in nucleophilic substitution reactions.
- Activated water-soluble polymer derivatives are created through the reaction of a water-soluble polymer with an activated leaving group.
- a) Water-Soluble Polymers [0013] The hydrophilicity of a selected peptide is enhanced by conjugation with polar molecules such as amine-, ester-, ether-, hydroxyl- and polyhydroxyl-containing molecules. Representative examples include, but are not limited to, polylysine, polyethyleneimine, poly(ethyleneglycol) and poly(propyleneglycol).
- the present invention is further illustrated by reference to a poly(ethylene glycol) derivative. Several reviews and monographs on the functionalization and conjugation of PEG are available. See, for example, Harris, Macromol. Chem.
- the poly(ethylene glycol) useful in forming the compositions of the invention is either linear or branched.
- branched polymers which are incorporated herein by reference, can be found in the catalog of Shearwater Polymers, Inc., Huntsville, AL, as well as in U.S. Patent Nos. 6,437,025, 6,436,386, and 6,362,254.
- Exemplary PEG and PPG derivatives disclosed herein include, but are not limited to, PEG derivatives (e.g., alkyl-PEG, aeyl-PEG, acyl-alkyl-PEG, alkyl-acyl-PEG carbamoyl- PEG, aryl-PEG), and PPG derivatives (e.g., acyl-PPG, acyl-alkyl-PPG, alkyl-acyl-PPG carbamoyl-PPG, aryl-PPG).
- PEG derivatives e.g., alkyl-PEG, aeyl-PEG, acyl-alkyl-PEG, alkyl-acyl-PEG carbamoyl- PEG, aryl-PEG
- PPG derivatives e.g., acyl-PPG, acyl-alkyl-PPG, alkyl-acyl-PPG carbamoyl-PPG, aryl-PPG
- the hydroxyl group at one end of a linear PEG molecule, or at one end of the main chain of a branched PEG molecule is co alently attached to a methyl group.
- Preferred activated leaving groups are those that do not significantly encumber the transfer of the sugar moiety to the water-soluble polymer. Accordingly, preferred embodiments include:
- reaction mixture was stirred at 25 °C overnight and then evaporated to dryness on a rotary evaporator (water bath temperature maintained at 40°C). Another 100 mL of toluene was added and evaporated to remove all traces of phosgene.
- To the polymeric chloro formate was added 30 mL of dry toluene, 10 mL of methylene chloride, and 1.7 g (14.8 mmol) of l-hydroxy-7- azabenzotriazole (HO At) (Aldrich, St. Louis, MO), and the mixture was stirred vigorously. The reaction flask was then cooled in an ice water bath and 1.5 g (14.9 mmol) of triethylamine was added gradually.
